First off, Get ready to spend a TON of money. Stand alone isnt cheap. But, its the best way to get the potential out of your car. I have a bit of expierence with the tec-3, so if the tec 2 is similiar, go that route. Full VE tables, full monitoring, ect, very nice, but around 2500. They sponsored a car i just built, and have been extremly helpful. I might be able to get a remaned tec 2 at a reasonable cost, I plan on it for my toyoya, if I ever get there........
